Description

Multi-mode scanning gun oriented to power equipment and working method thereof Technical Field The invention relates to the technical field of power inspection and management, in particular to a multi-mode scanning gun oriented to power equipment and a working method thereof. Background The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. In the scenes of asset management of electric equipment, inspection of metering devices and the like, a bar code scanning gun is one of core tools. For example, in a scenario of centralized boxing of electric energy meters, transformers and other devices, centralized storage, turnover and box sealing of a plurality of electric power devices are generally performed by using a corresponding electric power turnover box, wherein the electric power turnover box is used as a basic storage unit for storage logistics operation of a metering center and is used for storing qualified, to-be-rechecked and unqualified single-phase electric energy meters, three-phase electric energy meters, low-voltage current transformers and the like. Because the equipment information bar code is usually attached to each piece of electric equipment, the electric equipment is oriented to a plurality of pieces of electric equipment in the turnover box, and staff scans all the pieces of equipment by using a bar code scanning gun, so that the management of the electric equipment assets is realized by scanning large-scale equipment assets. However, the existing scanning gun has certain limitations in operation, which results in problems of low operation efficiency, confusion of data management and the like, including: (1) A single batch scan is inefficient and difficult to effectively address batch scan tasks. That is, the existing scanning gun generally adopts a one-shot scanning mechanism, only a single bar code of a single device can be read each time, a worker needs to scan each device one by one, time and labor are consumed, and the timeliness requirement of large-scale asset inventory in the power industry cannot be met. In addition, although the existing part of industrial-grade scanning guns (such as HS305 DP) can optimize the recognition capability of complex and tedious bar codes through the AI technology to realize batch scanning of equipment in a warehouse, the industrial-grade batch scanning equipment scans equipment sequentially conveyed on a conveyor belt one by arranging a plurality of scanning windows, and the industrial-grade scanning equipment is large in size and cannot carry out portable batch scanning. (2) The laser scanning area is fixed, and the barcode distribution of multiple areas or complex layout cannot be dynamically adapted. When facing different types of power equipment (such as 9/12 epitope electric energy meter and 3/6 mutual inductors), the fixed scanner can improve the scanning efficiency, but is difficult to adapt to dynamic space change when the power equipment is packaged due to different packaging positions of the power equipment and different bar code distribution, and if manual single batch scanning is adopted, the position of a scanning gun is also required to be manually adjusted, so that the scanning laser can accurately align with the bar codes to finish scanning, and the whole process is complex and the scanning efficiency is low. (3) The repeated scanning detection mechanism is missing, and the manual verification cost is high. The traditional scanning gun lacks a real-time anti-duplicate detection function, and when the same equipment is repeatedly scanned, the error can be found only by relying on manual check or double collaboration, so that human resources are wasted and the operation flow is redundant. For example, in the field of storage of metering equipment, although the efficiency can be improved through a fixed scanner, the anti-weight function of the metering equipment needs to rely on secondary verification of an external system, and alarm prompt cannot be directly realized at a scanning end. (4) The data management function is weak, and the traceability and the exporting capability are insufficient. The existing equipment generally lacks a localization data storage and flexible export function, and the scanning record needs to be processed by an external computer or a cloud system. For example, although a scanning gun supports multi-protocol connection, the data storage of the scanning gun depends on external equipment, and the operations of inquiring, screening and exporting the history record cannot be independently completed. In addition, the specific requirements of the power industry for data formats (e.g., excel/TXT) are difficult to meet with a common scanning gun, additional development interfaces are required, and technical complexity is increased. (5) Environmental adaptability and industry customization are lacking. Although the existing par
